Elastic modulus and Poisson’s ratio (in brackets) of different confining pressures and rock sizes.

Rock size	Confining pressure 200 kPa	Confining pressure 400 kPa	Confining pressure 800 kPa
16∼20 mm	22 (0.46)	28 (0.44)	46 (0.43)
10∼16 mm	16 (0.45)	27 (0.44)	46 (0.43)
5∼10 mm	14 (0.45)	25 (0.44)	42 (0.43)
Mixed size	13 (0.45)	23 (0.44)	44 (0.43)
